2007 R56 base not S. I replaced the front control arm bushings, front and rear sway bar bushings. When I backed it out of the garage and turned hard left the DSC failed light came on. I pulled it back in the garage and checked to see if there was anything I missed. NO. Started it up no DSC failed light, backed out and turned again and DSC failed came on again and stays on. As I've been checking to see if I could find a problem. The bake pad worn indicator now is on. They both now stay on even if I disconnect the battery and clear it out. Car is up in the air with no wheels and now I have a P0503 Vehicle speed sensor. I've checked the fuses, brake pads & sensors, the ABS sensors all seem to be okay. Any ideas?

 

You didn't happen to pinch a wire when you put eveything back together did you? If one of the sensor wires is pinched (or disconnected) then it will disable some things.

 

how did you repair this Goodies?

 

I didn't see any pinched wires when I looked. All the sensors aren't pinched. The wiring to the steering box doesn't look pinched. Maybe I should look again.

 

The only error code youre getting is V speed sensor?

Any chance you stretched the ABS sensor? Did you unplug and replug it in?

Do you have a scan tool to try and clear the code?

 

Did you partially drop the subframe to do the control arm bushings? There would have been some sensors in the passenger side wheel well you could have disconnected or stretched. Check those first. Were you messing with the steering wheel while the steering shaft was disconnected?

Wheel Speed Sensors..... check them..

 

No pinches. I've unpluged and repluged in the sensors. I checked the sensors they look good. I've cleared the code. I did drop the subframe partially. I did move the steering wheel 180 to get the shaft to lineup.

 

So you cleared the code and it came back?

I think you have no choice but to change the speed sensors one a time and see which one has failed.

 

You can check the speed sensors. Unplug the connector and hook the pins up to a
oscilliscope or an analog voltmeter - you can see the pulses when you spin the wheel
on the good ones. Or at least check the resistance and see which one is open or shorted
or markedly different from the others. Dealer level scan equipment can give a code that
is specific to the particular wheel involved.

 

Or get a scan tool like BMWhat ($45 + $20 adapter) and then see the code and work from there.

Or guess and waste time and money.

 

Bought a icarsoft 910II. It doesn't connect to car. but when I was messing with it I got a steering angle of -1175 the next time I got 360 then 0 when I turn the wheel it stopped changing.
New troubles turned the ignition on and the wipers started running and wouldn't stop. after turning it on and off several times they did stop.
I think I may have pulled a harness loose or something. Will start looking for that next.

 

Goodies,

How about a little context? Were you calibrating your steering angle? Sounds like you didnt complete the calibration.

I had the same symptoms after I changed all the front end bushings and ball joints etc. It wasn't till I got a new SZL that the problem went away.

I couldn't get my Auto Enginuity software to engage the calibration process after I worked on the front end. Then unfortunately I broke the volute spring in the SZL like a total rookie, got a new SZL, installed it and the issue you speak of (wipers wont turn off, turn signals wont disengage) resolved itself without even reprogramming the new SZL but the DSC! and BRAKE lights are still on/yellow. The reprogramming I am having done Wednesday by a local shop.

Actually with the new SZL installed, the wipers work normally now but the turn signal wont stop blinking if I turn 90 degrees for example and then straighten out. They will stop blinking after changing lanes only (small steering wheel angle change).

Let us know how you resolve.

 

I am a rookie at these cars.
I haven't been able to do anything with the icarsoft tool, except look at some things. One of the things I was looking at was the steering angle it was -1175 the first time I looked at it and it would change when I moved the wheel. The second time I looked at it it read 360 and would change with the wheel. The last time I looked at it it read 0 and wouldn't change. How does wipers, DSC, & brake light relate to the dropping of the subframe? Let me know if the local shop has anything to say that might help.

 

I'm new to these cars. I only bought this thing for my lady some months ago and have never owned a BMW or Mini.

MY SUPPOSITION is that when you drop the frame (and change our virtually everything that wears out, like I did) it throws the alignment out so badly that the steering angle becomes erroneous and therefore the DSC cannot work because the car doesnt know which way the front wheels are positioned relative to the rear etc and so DSC is shut down.

Okay, but what about the P2402, P0503 or the brake pads light, or the wipers, these things happened shortly after the DSC.
Where did you get the SZL?
If your local shop has any info when they reset it please pass it on. Thanks

 

Bro you're telling me that after plugging in the scan tool you generated all of those codes and a check engine light?

Cheapest new SZL I found was from ECS Tuning. $400 delivered.

The shop is going to program the SZL. But that doesn't have anything to do with brake pads.

 

The lights happened when I first started the car after dropping the subframe. My cheapo DTC tool got the codes when I plugged it in the first time. The Icarsoft 910II doesn't read any codes. it says no communication. It did show the steering angle but now doesn't show that just 0.

 

Does the Icarsoft allow you to calibrate the steering angle? If so, did you?

If not, then thats your issue. You need to recalibrate the steering angle. That will stop the wipes from going nuts and turn of the DSC/BRAKE error lights.

As for the Brake Pad light: Did you forget to reconnect the brake wear sensors?

The tool says it can't communicate with the car.
So no I wasn't able to calibrate the steering angle. The only thing I can read with it is some pin voltages. I was able to look at the steering angle but now can't. Here is a list of the things the Icarsoft is suppose to do.
I don't see steering angle in the list unless there is a abbreviation for it.
The Icarsoft manual just tells you how to connect it and update the software, which I did.

I really appreciate your input.
I'm trying to figure this out.
I hate having to go to the dealer every time the car farts.

 

I wish I could help, but I don't the first thing about that Icarsoft. I think until you resolve the communication issue, you cant really proceed. Perhaps call them and see if they can help you connect.

 

Update:

I brought the car into an aftermarket shop that specializes in BMW and Mercedes and they had an OTC brand J-2534 capable programmer (something like this I suppose ) and they programmed the new SZL and calibrated the steering wheel position.

I wasn't there when they did it and the technician wasn't there when I picked up the car. The 3 foolios at the desk didn't know a damn thing about anything (glorified secretaries).

My DSC! and BRAKE light are now "gone". Cost me $112 for reprogramming. (Probably took them 15 minutes, but I wasn't there to witness the miracle).

So, I still don't know why I couldn't get the AE software to calibrate the steering angle in the original SZL (before I broke the volute spring). Was it because the old SZL had to be programmed again before being calibrated? I don't know. The programmer is $1000 plus software and I wasn't about to spend that for one time use.

All in all it was $400 for part+ $112 for reprogramming.

 

I took it to the dealer. The mechanic said that to recalibrate the steering angle. He had to pull the steering wheel, move the cable all the way to one side then all the way back, then back to center. Put the wheels to center and put it all back together. Before doing the reprogramming. This is all if the spring isn't broken. We shall see how much it will cost.
I just get the feeling when I'm talking to the mechanic that they're saying all this to justify the expense.

 

1. I dont know why you need to spin the cassette before you reprogram it. Thats just asking for trouble. Just turn the steering wheel.

2.You know how fast the air bag and steering wheel come out? If I was in the air bag theft business, I would exclusively steal Mini airbags.

a. disconnect battery (not necessary for thieves)
b. pop off air bag with a screw driver.
c. undo 2 connectors behind the air bag (thieves may now run away)
d. unbolt the steering wheel.
